Input
Prompt
Create a cooked, stylized shrimp matching the reference look (gentle “C” curve, short tail, smooth ring segments), but as a hollow shell that is openable for later filling. Units: millimeters. Scale: 1:1. Axes: +X = length (head→tail), +Z = dorsal/up. Origin at geometric center. Target size: total length 90 mm, max width 28 mm, max height 18 mm. Wall thickness: uniform 2.5 mm (±0.2 mm). Exterior: smooth “C” curve; 7–8 shallow rings (~0.6 mm grooves), soft sheen; no fragile appendages (no antennae/legs/eyes). Short rounded rostrum. Interior: continuous smooth cavity preserving 2.5 mm walls; no sharp edges. OPENING (clam-shell for filling): produce two halves (left/right) split along the YZ plane (parting line at mid-thickness) so they close like a clamshell. – Add a perimeter tongue-and-groove joint around the entire split: tongue 1.2 mm wide × 1.0 mm tall, with 0.30 mm radial clearance to the groove for easy press-fit. – Include 4 alignment keys (conical Ø6→5 mm, 2.5 mm depth) spaced along the perimeter, alternating pin/socket between halves. – Apply draft angles: 2.0° external, 1.0° internal, pulling away from the parting line. – Minimum fillets: R0.8 mm outside, R0.5 mm inside. Filling port (optional): add a Ø8 mm fill hole hidden at the head end, with 1×45° chamfer and a Ø10×1.5 mm recess to accept a plug (do not model the plug). Vents (optional): two Ø1.0 mm vents near the tail tip for air relief. Mesh/output: export two STL parts (left and right halves), watertight/manifold, no self-intersections, no flipped normals; all normals outward. Tessellation fine enough for 0.6–0.8 mm radii without over-triangulation. Orient each half with length along +X and back along +Z. Exclude: no bases/supports, no text, no inserts, no hinges; closure is via the perimeter press-fit.Units: millimeters. Scale: 1:1. Axes: +X = length (head→tail), +Z = dorsal/up. Origin at geometric center. Target size: total length 90 mm, max width 28 mm, max height 18 mm. Wall thickness: uniform 2.5 mm (±0.2 mm).

OPENING (clam-shell for filling): produce two halves (left/right) split along the YZ plane (parting line at mid-thickness) so they close like a clamshell. – Add a perimeter tongue-and-groove joint around the entire split: tongue 1.2 mm wide × 1.0 mm tall, with 0.30 mm radial clearance to the groove for easy press-fit. – Include 4 alignment keys (conical Ø6→5 mm, 2.5 mm depth) spaced
